Are suppressors leagal to use in bullseye? Just shot in my league tonight and the question popped up because someone is using, and did use tonight, a 9mm H&K with like a 5'' suppressor on it. Looked and sounded cool. We couldn't find any info at the time saying they are forbidden, figuring they are like a muzzle break and do not have rifling. Our league dosent count for anything NRA wise and is just an internal LE BE league. We figured the guy went through the hassle of getting the tax stamp, why not.
